Description
본 발명은, 성형체용 변성 수지 및 골프 볼에 관한 것이다.The present invention relates to modified resins for molded articles and golf balls.
최근, 에틸렌 단독 중합체, 에틸렌과 다른 올레핀과의 공중합체, 에틸렌과 불포화 카르본산과의 공중합체 등의 폴리올레핀계 수지는 다양한 분야에서 이용되고 있다. 예를 들면, 폴리올레핀계 수지에 수산화 마그네슘이나 수산화 알루미늄 등을 배합한 것은 난연성이 우수한 점에서, 전선의 피복 재료 또는 전기 전자기기의 부재에 이용되고 있다. 또한, 용도에 따라서는, 산 변성 또는 염기성 화합물을 첨가하는 등 하여 폴리올레핀계 수지의 개질이 널리 행해지고 있다.Recently, polyolefin resins such as ethylene homopolymers, copolymers of ethylene with other olefins, and copolymers of ethylene with unsaturated carboxylic acids are used in various fields. For example, polyolefin resin mixed with magnesium hydroxide or aluminum hydroxide is excellent in flame retardancy and is used as a covering material for electric wires or components of electrical and electronic devices. Additionally, depending on the use, modification of polyolefin resins is widely performed, such as by acid modification or addition of basic compounds.
염기성 화합물을 첨가한 수지로서, 예를 들면, 특허 문헌 1에는, 산 변성 폴리올레핀의 구아니딘 화합물의 염을 포함하는 난연성 수지 조성물이 개시되어 있다. 이 난연성 수지 조성물에 의하면, 난연성에 더해, 기계 특성에도 우수한 것이 기재되어 있다.As a resin to which a basic compound has been added, for example, Patent Document 1 discloses a flame-retardant resin composition containing a salt of a guanidine compound of acid-modified polyolefin. According to this flame retardant resin composition, it is described that in addition to flame retardancy, it is also excellent in mechanical properties.
또한, 특허 문헌 2에는, 에틸렌-비닐에스테르계 공중합체 비누화물, 및 염기성 아민 화합물을 함유하는 에틸렌-비닐에스테르계 공중합체 비누화물 조성물이 개시되어 있다. 이 조성물을 함유시킨 재료는 폴리에스테르계 수지와의 접착성이 향상되기 때문에 다층 구조체에 유용한 것이 기재되어 있다.Additionally, Patent Document 2 discloses a saponified ethylene-vinyl ester copolymer and a saponified ethylene-vinyl ester copolymer composition containing a basic amine compound. It is described that materials containing this composition are useful for multilayer structures because their adhesion to polyester resins is improved.
게다가 또한, 특허 문헌 3에는, 폴리올레핀에 구아니딘 인산염을 첨가한 폴리올레핀계 수지 조성물이 개시되어 있다. 이 폴리올레핀계 수지 조성물에 의하면, 연소 시의 부식성 가스의 발생을 억제하면서 우수한 기계 특성을 실현할 수 있는 것이 기재되어 있다.Furthermore, Patent Document 3 discloses a polyolefin-based resin composition obtained by adding guanidine phosphate to polyolefin. According to this polyolefin-based resin composition, it is described that excellent mechanical properties can be realized while suppressing the generation of corrosive gas during combustion.
한편, 에틸렌과 (메타)아크릴산과의 공중합체를 금속 이온으로 중화(中和)한 아이오노머는, 높은 경도와 반발 탄성을 가지는 점에서, 골프 볼 등을 구성하는 탄성 재료층에 이용되고 있다(특허 문헌 4 참조). 골프 볼에서는, 투피스 볼, 스리피스 볼, 또는 포 피스 볼과 같은 중심부의 코어를 복수의 탄성 재료층으로 피복하여, 최외층 커버를 마련한 다층 골프 볼이 주류이다.On the other hand, ionomer, which is a copolymer of ethylene and (meth)acrylic acid neutralized with metal ions, has high hardness and rebound elasticity, and is used in the elastic material layer constituting golf balls etc. ( (see patent document 4). Among golf balls, multilayer golf balls, such as two-piece balls, three-piece balls, or four-piece balls, in which a central core is covered with a plurality of elastic material layers and an outermost layer cover is provided, are the most common.
다층 골프 볼에 있어서, 코어, 커버층, 코어와 커버층과의 사이의 층(중간층)의 재질은, 볼의 반발력, 초속도, 비거리, 스핀 성능, 및 타구감에 영향을 준다. 일반적으로는, 코어에는 부타디엔 고무, 중간층에는 아이오노머계 수지, 커버층에는 우레탄 수지나 아이오노머 수지가 사용되고 있다. 각각의 층에 이용하는 재료를 적절히 선택하고, 조합함으로써, 각각의 골프 볼 브랜드에 특징적인, 반발력, 초속도, 비거리, 스핀 성능, 및 타구감이 조절되고 있다.In a multilayer golf ball, the materials of the core, the cover layer, and the layer between the core and the cover layer (middle layer) affect the ball's repulsion force, initial speed, distance, spin performance, and feel. Generally, butadiene rubber is used for the core, ionomer resin is used for the middle layer, and urethane resin or ionomer resin is used for the cover layer. By appropriately selecting and combining the materials used in each layer, the repulsion force, initial speed, distance, spin performance, and shot feel characteristic of each golf ball brand are adjusted.
그러나, 상기 특허 문헌에 기재된 기계 특성이 우수한 수지를 골프 볼 등의 볼 재료로서 사용하기 위해서는, 반발 탄성률, 경도 및 굽힘 강성률에 있어서, 더욱 개량의 여지가 있다.However, in order to use the resin with excellent mechanical properties described in the above patent document as a ball material such as a golf ball, there is room for further improvement in terms of rebound modulus, hardness, and bending rigidity.
본 발명은 상기 사정을 고려하여 이루어진 것이며, 반발 탄성률, 경도 및 굽힘 강성률이 우수한 성형체용 변성 수지 및 그 성형체용 변성 수지를 이용한 골프 볼을 제공하는 것을 목적으로 한다.The present invention was made in consideration of the above circumstances, and its purpose is to provide a modified resin for a molded body with excellent rebound modulus, hardness, and bending rigidity, and a golf ball using the modified resin for a molded body.

[실시예 2-3][Example 2-3]
성형체용 변성 수지 중의 탄산 구아니딘의 배합량을 8.34g(10.7질량%)으로 한 것 이외는 실시예 2-1과 마찬가지로 하여 성형체용 변성 수지를 얻었다.A modified resin for a molded article was obtained in the same manner as in Example 2-1, except that the amount of guanidine carbonate in the modified resin for a molded article was changed to 8.34 g (10.7% by mass).
에틸렌·아크릴산 공중합체의 카르복실기의 총 몰수에 대한 성형체용 변성 수지 중의 구아니디늄 이온의 몰비는 0.50이었다.The molar ratio of guanidinium ions in the modified resin for molded products to the total number of moles of carboxyl groups in the ethylene-acrylic acid copolymer was 0.50.
[비교예 2-1][Comparative Example 2-1]
에틸렌·아크릴산 공중합체 (a2)를 탄산 구아니딘으로 변성하지 않았다.Ethylene/acrylic acid copolymer (a2) was not modified with guanidine carbonate.
상기 실시예 2-1~실시예 2-3, 및 비교예 2-1에 대하여 측정한 물성을 표 2에 나타낸다. 표 2 중의 「구아니디늄/산기」는, 에틸렌·메타크릴산 공중합체의 카르복실기의 총 몰수에 대한 성형체용 변성 수지 중의 구아니디늄 이온의 몰비를 나타낸다.The physical properties measured for Examples 2-1 to 2-3 and Comparative Example 2-1 are shown in Table 2. “Guanidinium/acid group” in Table 2 represents the molar ratio of guanidinium ions in the modified resin for molded products to the total number of moles of carboxyl groups of the ethylene-methacrylic acid copolymer.
표 2에 나타내는 바와 같이, 에틸렌·아크릴산 공중합체를 탄산 구아니딘으로 변성한 실시예 2-1~실시예 2-3은, 탄산 구아니딘으로 변성하고 있지 않은 공중합체의 비교예 2-1에 비해, 반발 탄성률, 쇼어 D 경도 및 굽힘 강성률 모두 높은 값이 얻어졌다.As shown in Table 2, Examples 2-1 to 2-3, in which the ethylene-acrylic acid copolymer was modified with guanidine carbonate, showed resistance compared to Comparative Example 2-1, which was a copolymer that was not modified with guanidine carbonate. High values for elastic modulus, Shore D hardness, and bending stiffness were all obtained.
상기한 바와 같이, 본 발명의 에틸렌·불포화 카르본산 공중합체를 탄산 구아니딘으로 변성한 수지는, 반발 탄성률, 경도 및 굽힘 강성률이 우수한 것이다.As described above, the resin obtained by modifying the ethylene/unsaturated carboxylic acid copolymer of the present invention with guanidine carbonate is excellent in rebound modulus, hardness, and bending rigidity.
